To all whom it may concern:

Be it known that I, FRANK ALBERT TTOUCK, a citizen of the .United States of America, and resident ofthe city of Ketchilittll, Territory of Alaska, have invented certain new and useful Improvements in Power-Gurdies, of which'the following is wa specification.

My invention relates to gin-dies and consists of a 'gurdy so designed as to be applicable to power driven boats, and .to be turned by power taken from the propeller shaft.

The object. of my invention-is-to provide agurdy of such design thatit may be conveniently installed upon power drivenboats in such a way asto be ,driven'from the propeller shaft- -and to provide such driving means of a character that the operation of the gurdy may be conveniently controlled by the man who is, attending to the lines.

In the accompanying drawings I have shown my invention in atype of construction well adapted for this purpose and which I now prefer to use.

The features of this device which I believe to be novel andwhich-I wishgto patent will be first described. and then particularly pointed out in'the claims.

Figure l'is a longitudinal sectionsthrough the rear portion of a boat, showing the manner of installing my deViceand its construction.

Fig. 2 is a section taken in a plane transversely ofthe'boat, justa'earward of the friction driving mechanism, and :looking forwardly,.or toward the bow.

F 3 is a. sin'iilar-section takenonvthe same plane but looking rearwardly, or toward the stern.

F 4 is a top viewofthe holding head and its associated parts.

In=the drawings 1 represents the propeller shaft. This, at the rear end of the boat-goes through a portion 2 of the'frame of theboat, which is ordinarilycalledthe scag. The forward end of this, which is the rearmost point at which the propeller shaftis accessible within the boat, is located some distance forwardly of the point Where it'is desired to locate the gurdy.

The holding head consists of a pulley or drum 3, and the two guide pulleys 30 and 31. These are mounted in the relative position shown in Fig. 4 and are installed upon the rear of the boat close to the stern, The

guidepulley 30 islocated where the line may be conveniently run thereon as it is being. hauled in .an'dso as to direct the line on leaving the. same. to' the holding head 8.

The guidezpulleys 3O and 31 aremounted upona plate, .45, which is of rolled metal and mounted to swing upon the hub 46* of the hauling head. This plate may beswung so as to place: the outbound guide pulley 30 well over the'outer edge. of the rail, or.in- 'wardeosas'to bring everything within the nails outer edge so that it will not be engaged. by a doclcwhen lying .alongside. A P111 47 serves torsec-ure this plate in either position being adapted to enga e with either 0f:tWO.-SOCk6tS 48 located at the inner and outer edges of the rail.

The holding head 3 is designed to apply its power to haul the line by means. ofrfrictional engagement of the line therewith. F or thispurpose it Inay'beprovided with .a groove into whiclrthe line maydrop and thus be frictionally grasped by the side walls thereof. Theguidepulleys 30and 31. are so placed as to give as large an arc of contact of the -,line withthe head 3 asmaybe conveniently. secured.

The head 311's connected bythe mechanism illustratedin the drawings with the propel- ]er.-shaft so as-to be turned thereby. The line, :after passing over the holding-head is coiled eitheiwupon the deck orlin a boxer other container. r

The; shaft 34 of the'holding head isfjournaled; inacasting 83 which. is secured on. the rail, the shaft extending; downward a through the d-ecklofthe boatiandat its lowerend has thereon a bevel gear r35,which meshes with a bevel gear 42whichissecured to one section 40of mtGlQSOOPlC shaft. Theother sectionofthe shaft. is herein shown as bein a pipe 4 into which .the :shaft 40 enters? whereby they may have relative lengthwise movement. The adjacent GITClS OfifllG two shafts 34 and 40 are journa-led within a frame member or casting, as 43,-\vl1ich niay beiseeured to tlieside ofztheiboat orzto any convenient support. I

It-is @desirable that the driving mechanism, which COIHIGCtSvthG holdinghead with the .propellei shaft, contain 'a resilient or yielding member, so z't-hat if the line, iwhile being 5 hauled in, should in: any manner the come suddenly checked, the holding head will be stopped or momentarily checked and the line will not become broken. or this section has been employed. To secure the i be employed for holding the transmission other accepted alinement enough 7 combined facesof 8, may be slid axially enough todisengage 1t bythe frictionpinion 6; This pinion,

reason and also for convenience in adjust ing the transmission mechanism to boats of differing size and design, the telescopic shaft yielding action I employ a helical spring ll, which surroundsboth sections and has one end secured to each of these shaft sections.

The telescopic shaft is connected by a universal joint 14 with a shaft 5 which is journaled in a yoke 50,'pivoted at 51 and adapted to swing in a fore-and-aft direction. Mounted upon this shaft is a small friction gear or pinion 6, this being connected with the shaft by a key and keyway, or by any 'means which will permit shifting of the pinion lengthwise of the shaft while maintaining the two so as to turn together. For shifting, he common expedient of a grooved collar 60 upon the pinion and a control lever 61 is employed. This lever '61 is pivoted at 62 upon the front side of a bulkhead 10. Adjacent the pivot it is laterallybent and passes through the bulkhead, having its operating end outside the bulkhead convenient to the cock-pit 11, in which the operator works.

' Cooperating with the friction pinion 6 is a friction disk 63 which is mounted upon a shaft, as 7 which extends fore and aft and which is connected with a jack shaft by a universal coupling 71. Upon the forward end of the jack shaft 7O is a spur gear 8 Upon the propeller shaft is a spur pinion 80. These are connected by an intermediate pinion 81 which is provided with'a grooved collar 82 by means of which the pinion may be shifted so as to slide it lengthwise out of engagement with one of these gears. The pinion and the gear 8 are placed out of so that the pinion 81, which is of a breadth of face equal to the the pinion 80 and gear from one of these while maintainin en a ementwith the other, and may, in proper position, engage bothq V Y Any convenient means for shifting this pinion-may be employed. That shown con-L sists of a rod'85 WlllOll at its forward end is laterally bent to engage with a collar or ring 83 which fits between grooved hub 82 of" pinion 81. This rod extends to the cock-pit and has a handle end 87 which maybe secured tion, as by teeth on the rod and a holding dog 88. Any other suitable means may gears just described in engagement.

' Upon the "rear end of the shaft T's afric-.v

tion disk 63 which is adapted to be engaged being the telescopic shaft I the fiangesof the in adj u-sted posi mounted in the swinging yoke 50, may be caused to engage anddisengage with the driving disk 63 as desired. To control. this fhave shown a rod 52 which passes through the bulkhead 10 and is connected with a bell crank controlling lever 53. A spring, as 54, is employed for normally holding the friction pinion 6 out' of engagement with the disk 63.

When it is not desired to use the gurdy, the intermediate driving pinion 51 is shifted so as to be disengaged from the driving pinion 80. The entire mechanism is thus thrown out of action. By employing a friction driving device of such character as the disk 63 andpinion 6, and locating this so that its normal tendency is to be disengaged, the operator can conveniently control the action of the gurdy by holding the pinion in engagement with the disk "whenever he wants-to haul in upon a line. By employing the resilient or yielding transmission member represented by the spring 41, sudden shocks which wouldover-strain the line and break it may beavoided'. The same results: to a certain extent may be secured by applying the friction driving lightly. However, the use of a yielding member such as the spring 11 is very desirable in addition to the friction driving clutch.

In using the gurdy the line is placed. over the outer guide pulley 30 about the holding head 3 and the guide pulley 31. It thus has a sufficient engagement with the holding head 3 to enable the latter to pull in the line. The strength ofthe pull which may be thus communicated to the line will, of course, depend somewhat upon the pull which is given to the line in removing it from the gurdy. Asthese line guiding and holdingmeinbers are supported only from one side the line may be conveniently passed abouttheni. 1
